SPECIFICATION forming part of Letters Patent No. 659,237, dated October9, 1900.

7 Application filed May 18, 1900. $erial No. 17,182. (No model.)

To all whom, it may concern:

Be it known that I, ANDERS J. KETELSEN, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Miners Separating-Pans;and I do declare the following to be a full, clear, and" exactdescription of the invention, such as will enable Others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

Thisinvention relates to a simple and novel attachment adapted to beapplied to and used in connection with a miners separatingpan toseparate the iron or other ore from any gold that might be containedtherein after the earthy matter and gravel have been washed therefrom bythe usual process.

The invention has for its primary object the provision of a magneticseparator attachment adapted to be supported from the top of a pan andproject down into the body portion thereof into approximately a centralposition therein and in means for rotating or agitating the separatorfor extracting the iron or other mineral ore from the gold.

In the accompanying drawings an embodiment of the invention isillustrated, and in hereinafter referring to the same like letters ofreference will designate corresponding parts in both views.

Figure 1 is a vertical sectional view of a pan with the inventionapplied thereto, and Fig. 2 is a plan View of the same.

Referring more specifically to the drawings, A denotes a suitable pan asordinarily employed by miners for washing or separating the earthymatter and gravel from the ore. Adapted to rest upon the edges of thispan is a brace or supporting bar B, provided at one end with books 0,adapted to engage over the beaded edge of the pan, and an offset portionE at its opposite end is adapted to rest upon the edge of the pan. Thisrod also has an extended portion b, which constitutes a handle forelevating the separator when it is desired to detach the same from thepan, and it may also be found desirable in steadying the separator whilethe same is being operated. Passing through the central portion of thissupporting-bar and rigidly attached thereto is a tube E. This tube iselongated and constitutes a bearing for the shaft F, which supports androtates the magnetic steel separator-blades G. The upper end of the rodF is provided with a suitable crank H or other rotating means. The crankand shaft may be of any suitable material, steel being found preferable,owing toits strength; but in order to prevent the accumulation ofmaterial around its lower bearing the tubular bearing is preferablyformed of brass or other non magnetic material, and the magnetic steelblades are secured to the lower end of the operating-shaft through themedium of a brass block or joint J, internally screwthreaded forattachment to the operatingrod, as will be clearly seen in Fig. l. Themagnetic steel blades may be of any configuration found desirable forthe use to which the separator is put; but in the present instance Ihave found that blades serrated or cut out on theirloweredges, as shown,ofler an extended magnetic surface upon a relativelysmall blade. Anynumber of these blades may be employed; but for simplicity inillustration only two are shown in the drawings.

It will thus be seen by a very simple attachment I have provided anefficient separator for use by what are commonly known as prospectors.The attachment may readily be applied and detached from any of theordinary miners pans, and when once applied and agitated the magneticarms will attract the small iron particles of ore or other metal whichmay be contained therein, and thereby thoroughly separate the same fromthe gold particles, it being understood that the earthy matters andgravel having been previously washed therefrom.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

1. In combination with a suitable separator-receptacle, a detatchableseparator adapted to be supported from the top of the receptacle,comprising a supporting-bar having hook portions adapted to engage theedges of the receptacle, a tubular bearing on said supporting-bar,magnetic separator-blades rotatably mounted in said tubular bearing andmeans for operating the blades, snhstanthe rod, magneticseparator-blades supported tially as described. centrally of said barand adapted to project 2. In combination withapan or like recepinto thepan and means for agitating the tacle, a detachable separator adapted tobe blades, substantially as described. 5 supported upon the pan andprojected there- In testimony whereof I have affixed my [5 intocomprising a brace-bar having a hooked signature in presence of twowitnesses.
